Limited Partner (LP)
Last updated 17 July 2026
A limited partner (LP) is an investor in a private markets fund who provides capital but plays no role in managing it. Most private equity, venture, credit, and real estate funds are structured as limited partnerships: the general partner (GP) makes the investment decisions and runs the fund, while the LPs commit capital and, provided they stay out of management, their liability is designed to be limited to the amount they committed. The LP's rights and obligations are set out in the limited partnership agreement, sometimes supplemented by a side letter negotiating specific terms such as fees or reporting.
Why it matters for family offices
Family offices are among the most active LPs globally, and managers often value them for patient capital that does not need to be returned on an institutional timetable. Being an LP is administratively demanding, though. Each position carries an unfunded commitment that can be called at short notice, and each generates its own stream of paperwork: capital call notices, distribution notices, quarterly capital account statements, audited financials, and tax reporting. The office must track called versus uncalled capital across every position, verify that each notice matches the agreement, and feed manager-reported values into the family's consolidated reporting, typically on a quarterly lag.
How it shows up in practice
Picture a family office holding LP interests in twenty funds across several family entities. In a typical quarter it might receive a handful of capital calls, several distributions (some of them recallable, meaning the GP can call that money again), and twenty capital account statements in twenty different formats. Reconciling all of this by hand in spreadsheets is where errors creep in: a call paid from the wrong entity, a distribution never matched to its fund, a stale valuation carried forward. Offices that centralise LP position tracking maintain one live record per fund, covering commitment, calls, distributions, and current value, so questions such as the family's total unfunded exposure have an immediate answer.
Related terms
General Partner (GP)
The manager of a private markets fund, responsible for sourcing investments, making decisions, and running the fund's operations. The GP typically earns a management fee plus carried interest, and usually invests its own capital alongside investors to align incentives. Assessing the quality, track record, and alignment of the GP is the heart of fund due diligence.
Capital Call
A demand from a private markets fund for investors to pay in a portion of their committed capital, usually to fund a new investment or fees. Calls arrive on short notice, typically ten business days, and missing one can trigger severe penalties. Family offices track expected calls closely to ensure cash is available without disturbing the portfolio.
Capital Commitment
The total amount an investor contractually agrees to provide to a private markets fund over its investment period. The fund draws the commitment gradually through capital calls rather than collecting it upfront. Monitoring unfunded commitments across dozens of funds is critical for family office liquidity planning.
Side Letter
A private agreement between a fund and an individual investor granting terms beyond the standard fund documents, such as fee discounts, co-investment rights, enhanced reporting, or transfer permissions. Large or early investors, including family offices, routinely negotiate side letters. Tracking the specific rights held in each fund is part of disciplined private markets administration.
Unfunded Commitment
The portion of a capital commitment that a fund has not yet called, and which the investor must stand ready to pay on short notice. Across dozens of funds, unfunded commitments add up to a substantial contingent liability that shapes how much cash and liquid assets a family must hold. Monitoring total unfunded exposure in real time is a core private markets reporting requirement.
