A family office is the professional structure that manages the wealth of a business family: investments, taxation, succession and governance. It can serve a single family (single family office) or several that share a team and costs (multi family office). Its distinctive feature is the horizon: it invests over decades, not quarters.
This fact sheet defines the role and explains how it invests. If you run a family office and what you are looking for is the process to analyze and incorporate tokenized assets into the portfolio, that part is in tokenization for family offices.
What a family office does, beyond investing
Investment is the visible part, but the mandate is broader. It consolidates wealth dispersed across companies, real estate and portfolios. It plans succession between generations. It organizes the taxation of the whole. And it provides governance for family decisions, with protocols and councils that separate the family from management.
Many are born after the sale of the family business, when wealth shifts from shares in a company to liquidity that must be structured. That origin explains their bias: they think like entrepreneurs who no longer want to operate, but do want to understand every asset they enter.
Single or multi: two structural models
| Aspect | Single family office | Multi family office |
|---|---|---|
| Whom it serves | A single family | Several families |
| Team | Proprietary and dedicated | Shared among clients |
| Cost | Fixed and high; only pays off with large wealth | Variable; shared among families |
| Personalization | Total | High, with standardized services |
There is no legal wealth threshold to set one up. Industry practice places the single family office at estates of tens of millions of euros; below that, the multi family office provides the same function at shared cost.
How a family office invests
The first objective is not to beat an index: it is to preserve wealth and grow it above inflation for generations. That priority explains two traits. First, diversification between liquid and illiquid assets, with a significant weight in alternatives: direct real estate, private equity, private debt and infrastructure. Second, the preference for direct investment or co-investment when the team can analyze it: fewer fees and more control over the asset.
The long horizon makes illiquidity acceptable. A ten-year fund or a four-year development are not a problem for someone who does not need the capital tomorrow. The filter is elsewhere: the quality of the asset, of the manager and of the legal structure that supports the investment.
In Spain, the usual structure combines a family holding company with separate vehicles by asset type. The internal team filters the opportunities; external specialists, private banks, asset managers and law firms, execute. That architecture explains its way of deciding: slow processes, deep analysis and few transactions per year.
Why family offices are looking at tokenized assets
There are two operational reasons and one regulatory reason. The first is access: tokenization fractionalizes assets that previously required industrial-sized tickets, and allows building smaller positions in more assets without changing risk profile. The second is the registry: the position is recorded in a blockchain-based system maintained by an ERIR, the digital notary of the registry, with traceability of ownership from issuance (Ley 6/2023; RD 814/2023). Consolidating positions spread across different custodians and registries is an expensive part of a family office's work; a single registry with traceability reduces that cost.
The regulatory reason avoids misunderstandings: a token with economic rights of a share, bond or participation is a financial instrument, with the same protection framework as its traditional equivalents (MiFID II, Annex I). For an institutional investor that is not a limitation: it is the condition for entering. The full workings of the model are in the asset tokenization guide.
The bottom line: a family office does not buy tokenization, it buys assets. Faced with a tokenized opportunity, the right questions are the usual ones: what asset is underneath, who manages it and what rights the instrument incorporates.

Frequently asked questions
What is a family office?
It is the professional structure that manages the wealth of a business-owning family: investments, taxation, succession planning and family governance. It can serve a single family, the single family office, or several that share a team and costs, the multi family office. It invests with a horizon of decades and priority on capital preservation.
How much wealth is needed for a family office?
There is no legal threshold. The single family office, with its own dedicated team, only pays off from wealth in the tens of millions of euros because of its fixed cost. The multi family office gives access to the same function with smaller fortunes, because the team and costs are shared among several families.
Why do family offices invest in tokenized assets?
For access and operations: tokenization fractionalizes the entry ticket in real assets and records the position in a traceable registry maintained by an ERIR, under Ley 6/2023. The instrument remains a regulated security, with the same protection as a share or a bond, and that fits the institutional profile of these investors.
