External Advisers
Last updated 17 July 2026
External advisers are specialists engaged from outside the family office to provide expertise, execution, or an independent view. The network can include lawyers, tax advisers, accountants, bankers, investment consultants, insurance brokers, security professionals, and property specialists. Some are retained over many years, while others are appointed for a particular transaction or jurisdiction.
An adviser does not need to sit inside the office to become important to its work. Complex families depend on these relationships because no internal team can maintain deep expertise in every market, legal system, tax question, or technical asset.
Why it matters for family offices
The challenge is coordination. Two advisers can give individually reasonable recommendations that conflict when ownership, tax residence, investment policy, or family objectives are viewed together. The family office acts as the informed client, defines the question, supplies accurate information, identifies dependencies, and makes sure agreed actions have an owner.
Selection and oversight also matter. The office considers competence, independence, conflicts, confidentiality, fees, and the jurisdictions covered. Access should be limited to what the adviser needs. A lawyer reviewing one trust does not automatically need full portfolio visibility, while an investment consultant cannot assess total risk from a partial asset list. Engagement terms and decision authority should remain clear.
How it shows up in practice
Suppose a family plans to buy a property through a holding company in another country. Local counsel reviews title and company law, tax advisers assess the ownership alternatives, a bank proposes financing, and an insurance broker evaluates cover. Each needs a consistent set of facts about the buyer, funding, intended use, and ownership chain.
The family office creates a controlled deal file, grants role-based document access, schedules a joint issues call, and records decisions. It notices that the bank's proposed covenant conflicts with the trust's limits on guarantees and asks the advisers to resolve the point before signing. Coordinated information prevents the family from becoming the messenger between disconnected specialists and preserves a record of why the final structure was chosen.

Family Office Services
The full menu of services a family office may provide, spanning investment management, consolidated reporting, accounting, tax coordination, estate administration, philanthropy, risk management, and lifestyle support. No two offices offer the same mix; each family decides what to keep in-house, what to outsource, and what to skip. Defining the service scope is the first step in designing or evaluating any family office.
Virtual Family Office (VFO)
A lean family office model in which a small core team, sometimes just the principal and one adviser, coordinates a network of external specialists such as lawyers, accountants, and investment managers. Technology plays a central role, replacing in-house staff with cloud-based platforms for data aggregation, reporting, and document management. VFOs are increasingly popular with first-generation wealth creators.
Outsourced Chief Investment Officer (OCIO)
An external firm or professional to whom a family delegates day-to-day investment management, including manager selection, asset allocation, and risk monitoring. The OCIO model gives families institutional investment capability without hiring a full in-house team. The family retains strategic control while the OCIO executes within an agreed mandate.
Tax Planning
The legal structuring of a family's affairs, through entity choice, residency, timing, and jurisdiction, to minimise tax liabilities across income, capital gains, wealth, and inheritance taxes. For UHNW families with assets and members in multiple countries, tax planning is a continuous, coordinated exercise rather than an annual event. It sits at the intersection of investment strategy, wealth structuring, and estate planning.
Estate Planning
The legal and financial arrangement of a person's assets to ensure they are transferred according to their wishes, with minimal tax friction and family conflict. Tools include wills, trusts, holding structures, and lifetime gifting strategies. For UHNW families, estate planning is a continuous discipline that must keep pace with changing laws, asset values, and family circumstances.
