Legal structure is one of the foundations of a durable family office. It determines who owns the office, who funds it, who employs staff, who has authority to act, how confidential information is protected, how services are provided, and which risks sit with which entity or individual. If the legal architecture is unclear, the family office may function informally for a period of time, but problems usually appear during stress: a dispute, employee departure, transaction, audit, death, divorce, regulatory inquiry, or generational transition.
This chapter focuses on the practical legal and contractual matters that should be addressed when setting up or redesigning a family office. The objective is not for the family office team to practice law. The objective is for the office to know which legal questions must be answered, which documents are needed, how responsibilities should be allocated, and when specialist counsel must be involved. Good legal design gives the office authority, protects confidentiality, supports controls, and reduces ambiguity before decisions become urgent.
19.1 Legal Entity Options for the Family Office
Family office entity: The legal vehicle through which the family office employs staff, contracts with vendors, pays expenses, receives funding, and delivers services. The entity may be newly formed or may sit within an existing family-owned structure. The best choice depends on ownership, liability, tax treatment, confidentiality, regulatory considerations, employment needs, and the family’s broader estate and governance structure.
Common options include a limited liability company, corporation, partnership, management company, administrative services company, or a structure affiliated with a trust, foundation, or family holding company. In some cases, the family office remains embedded within an operating business for a transitional period. That may be efficient, but it should not remain informal if personal, investment, trust, or family services are being provided at meaningful scale.
Limited liability company: A flexible entity often used for family office operations because it can provide liability separation, governance flexibility, and contractual clarity. It may be owned by the principal, a trust, a family holding company, or multiple family branches. The operating agreement should define ownership, management authority, capital contributions, expense obligations, transfer restrictions, and dissolution provisions.
Corporate structure: A company form that may be useful when the family wants a familiar governance model, employee infrastructure, board oversight, or clearer separation between ownership and management. A corporation may be appropriate in some jurisdictions or where tax, employment, or liability considerations support that choice.
The family office should avoid creating an entity merely for appearance. Every structure should have a purpose. Counsel should help determine where the entity is formed, who owns it, who manages it, how it is taxed, what activities it may conduct, and whether it creates regulatory obligations.
19.2 Ownership, Funding, Cost-Sharing, and Expense Allocation
Once the entity is selected, the family must decide who owns and funds the office. This is more than an accounting question. It affects control, fairness, tax treatment, family expectations, and accountability. A founder-funded office may be simple in the first generation, but complexity increases when multiple branches, trusts, entities, foundations, and adult beneficiaries receive different levels of service.
Ownership model: The legal and economic arrangement that determines who owns the family office entity and who has governance rights over it. Ownership may rest with one individual, a trust, a holding company, or several family branches. The ownership model should align with the office’s mandate. If the office serves multiple branches, the structure should define whether those branches have representation, voting rights, information rights, or funding obligations.
Funding model: The method by which the office receives cash to operate. Funding may come from direct contributions, management fees, expense reimbursements, service charges, investment entity allocations, trust reimbursements, or a central family vehicle. The model should be documented and reviewed by tax counsel and accountants to ensure that payments are properly characterized.
Cost-sharing: The allocation of family office expenses among individuals, trusts, entities, foundations, or branches. Cost-sharing should be based on a rational method, such as assets served, services consumed, transaction volume, headcount support, entity count, or agreed family policy. A simple equal split may feel fair but may not reflect actual use. A usage-based model may be more precise but can be harder to administer.
The family office should maintain written allocation rules for compensation, technology, office rent, travel, professional fees, investment support, bill pay, household services, and philanthropy administration. Expense allocation should be defensible, consistent, and understandable. Informal allocation can create tax concerns, branch resentment, and confusion over who is entitled to which services.
19.3 Employment Agreements, Confidentiality Agreements, and Non-Disclosure Agreements
Family office employees often receive access to the most sensitive information in a family’s life: assets, liabilities, residences, travel, medical matters, family disputes, personal preferences, tax records, estate plans, investment documents, passwords, security procedures, and private communications. Employment documentation must reflect that level of trust.
Employment agreement: A written agreement defining the employee’s role, reporting line, compensation, bonus eligibility, benefits, confidentiality obligations, termination provisions, expense policies, restrictive covenants where applicable, and ownership of work product. Senior roles such as CEO, CIO, CFO, COO, general counsel, and chief of staff should have particularly clear agreements because their authority and access are substantial.
Confidentiality agreement: A document requiring employees, contractors, household staff, vendors, and advisors to protect private information and use it only for authorized purposes. Confidentiality should cover financial records, legal documents, family information, entity records, security protocols, investment opportunities, advisor communications, and personal data. The agreement should also address return or destruction of information when the relationship ends.
Non-disclosure agreement: A contract used when sensitive information is shared with a third party, such as a consultant, investment sponsor, technology vendor, household employee, buyer, seller, lender, or co-investor. NDAs should not be treated as generic forms. They should match the sensitivity of the information, the relationship, and the permitted use.
Family offices should also address conflicts, outside activities, gifts, expense reimbursement, use of personal devices, remote work, information access, social media, and communications with family members. Senior employees may need provisions covering incentive compensation, severance, garden leave, non-solicitation, fiduciary obligations, and transition support. Household staff may require separate agreements tailored to residence access, children, travel, privacy, and safety protocols.
Documentation is only part of the control environment. The office should pair agreements with onboarding, training, access controls, periodic reminders, and termination procedures. When an employee leaves, access should be removed promptly, devices returned, files secured, passwords changed where necessary, and continuing confidentiality obligations reaffirmed.
19.4 Service Agreements Between the Family Office and Family Members or Entities
A family office often provides services to multiple recipients. Those recipients may include individuals, trusts, investment entities, holding companies, foundations, real estate entities, aircraft or yacht entities, and family branches. A written service agreement helps clarify what the office is authorized to do for each recipient and how costs, authority, liability, and confidentiality are handled.
Service agreement: A contract or written mandate defining the services the family office will provide to a person, trust, entity, foundation, or branch. It should specify scope, fees or reimbursements, information access, decision rights, limitations, confidentiality, reporting, termination rights, and responsibility for third-party costs.
Service agreements are especially important when the office serves entities with different owners or fiduciaries. A trust may require trustee approval before the office can act. A foundation board may need to approve administrative support arrangements. A family investment partnership may need documented cost reimbursement rules. A family member may receive personal administrative support, but the office should know whether that support is funded centrally or charged separately.
The service agreement should also clarify that the family office coordinates advice but does not replace licensed professionals unless it has qualified personnel authorized to provide that advice. For example, the office may coordinate tax information, but the tax firm prepares the returns. It may coordinate legal documents, but counsel provides legal advice. It may gather investment data, but the investment committee or authorized advisor makes investment decisions.
For multi-branch families, service agreements can reduce resentment. They make clear which services are standard, which are optional, which require separate payment, and which are outside scope. This prevents the family office from becoming an unlimited resource for whoever asks most forcefully.
19.5 Regulatory Considerations and When to Involve Counsel
Regulatory questions should be addressed early, not after the family office is already operating. The issues depend on the office’s activities, jurisdictions, ownership, clients served, compensation model, investment role, and whether services are provided only to family members or to outsiders. Even a private family office may face rules related to securities, investment advice, trust services, employment, privacy, tax reporting, anti-fraud controls, charitable activity, payroll, data protection, and cross-border matters.
Regulatory review: A legal assessment of whether the family office’s activities trigger registration, licensing, reporting, disclosure, compliance, or fiduciary obligations. This review should be refreshed when the office adds clients, manages pooled vehicles, accepts non-family capital, pays incentive compensation, sponsors direct investments, expands internationally, hires staff in new locations, or changes its service model.
Counsel should be involved whenever the family office forms entities, drafts governance documents, hires senior employees, structures compensation, manages confidential data, supports trusts, creates investment vehicles, participates in direct deals, engages co-investors, handles cross-border assets, or provides services to multiple branches or entities. Counsel should also be involved when there is a dispute, data breach, employment termination, regulatory inquiry, major transaction, or uncertainty about who has authority to act.
A practical legal readiness checklist should include:
- Entity formation: Confirm the family office entity, ownership, governance, tax classification, and authority to operate.
- Operating documents: Maintain operating agreements, bylaws, resolutions, consents, service agreements, and delegation of authority.
- Employment documentation: Use appropriate agreements, policies, confidentiality obligations, and termination procedures.
- Advisor contracts: Review engagement letters, fee terms, confidentiality provisions, liability limits, and data access rights.
- Regulatory triggers: Review investment advisory activity, pooled vehicles, non-family participation, fiduciary roles, privacy obligations, and cross-border issues.
- Recordkeeping: Store signed documents securely with clear ownership, version control, and access permissions.
The family office should maintain a legal document inventory and assign an internal owner for updates. Legal structure is not a one-time setup task. It must evolve as the family adds entities, changes advisors, hires staff, enters new investments, relocates family members, creates philanthropic vehicles, and moves through generational transition. A well-designed legal framework gives the office permission to act, boundaries for what it may not do, and records that future decision-makers can trust.
