Delaware LP or Cayman ELP for a VC or PE fund?
Last reviewed: 1 September 2026
For US-taxable LPs, a Delaware Limited Partnership under DRULPA is the default. For non-US LPs, US tax-exempt LPs (endowments, pensions), and sovereign wealth funds, a Cayman Exempted Limited Partnership is the default. Most funds with mixed investor bases run parallel Delaware and Cayman vehicles, or a Delaware main fund with a Cayman feeder.
The choice is a US tax question first. US-taxable LPs (individuals, most family offices) prefer Delaware to avoid PFIC and CFC complications. US tax-exempt LPs (endowments, foundations, pension plans) prefer Cayman to avoid UBTI on leveraged deals. Non-US LPs prefer Cayman to avoid US ECI exposure.
The Delaware LP is governed by DRULPA (Delaware Revised Uniform Limited Partnership Act). The manager is typically an SEC-registered adviser or Exempt Reporting Adviser under the Investment Advisers Act of 1940. The Cayman ELP is governed by the Exempted Limited Partnership Act and, if it accepts external capital as a closed-ended fund, is registered under the Private Funds Act with CIMA.
Cayman ELPs carry annual CIMA supervision, an audit by a Cayman-approved auditor, an AML officer appointment and FATCA/CRS reporting. Delaware LPs carry no fund-level regulator; the regulatory weight sits on the manager. Setup speed and cost is broadly comparable for a simple structure; complexity rises fast for parallel or master-feeder setups.

Frequently asked questions
When do I need both structures?
When your LP base includes both US-taxable and either non-US or US tax-exempt LPs at meaningful size. Parallel Delaware + Cayman or Delaware main + Cayman feeder is the standard pattern.
Which is cheaper to run?
Delaware, in isolation. Cayman adds CIMA supervision, audit and AML overhead. The trade-off is unlocking non-US and US tax-exempt capital.
Does Reuben AI handle parallel Delaware and Cayman?
Yes. Both vehicles are stored natively with pro-rata capital calls, NAV reconciliation and per-vehicle LP reporting.
Does a Cayman ELP need a Cayman general partner?
The GP is typically a Cayman exempted company or LLC. The manager (adviser) can be elsewhere and contracts to the GP.
