Yes. An LPA can usually be amended after signing, but the key issue is **whether the change is material**.

- **Usually no LP approval needed** for:
- ministerial fixes
- administrative cleanups
- non-material corrections

- **Usually LP approval is needed** for:
- material amendments
- major governance changes
- economic term changes
- significant version upgrades

Typical examples that may call for amendment:
- correcting drafting errors
- updating technical or administrative provisions
- changing governance mechanics
- revising fees, carry, or other economics
- changing core fund terms in a meaningful way

A common standard is **Majority in Interest** approval for major changes, but the exact rule depends on that LPA’s amendment section.
