What Your Co-Ownership Agreement Should Cover

Here are the topics your house co-ownership agreement should cover.

These are major decisions, which you'll want to think over and discuss in advance of committing them to paper. As friendly as things are now, consider worst-case scenarios: everything from a guest who won't leave to a natural disaster destroying the house to a sale when property values have dropped.

You'll probably want to prepare a separate attachment regarding house rules, such as guest policies and cleaning responsibilities.
