You generally cannot **guarantee** collection just by having an LP sign.

- The enforceable commitment is typically in the **LPA** and often the **Subscription Agreement**.
- Those documents should give the GP clear remedies if an LP defaults on a capital call, such as:
- default interest
- loss of voting rights
- dilution or forfeiture
- forced sale of the LP interest
- legal enforcement rights

In practice, the best protection is:
- strong LP diligence before closing
- clear capital call mechanics in the LPA
- consistent communication and follow-up

For legal drafting, work with fund counsel, since enforceability depends on jurisdiction and document structure. If using Decile launch workflows, LPs normally sign an **LPA**, not an SHA.
