When do my partner and I need to have a domestic partnership agreement?

A domestic partnership agreement isn't necessary if you haven't been together long or don't own much. But if you have been together a long time or consider your relationship to be long-term, it's important to clarify who owns what; especially if you've started to accumulate a lot of property. This will prevent an emotionally and financially draining court battle if you do split up. Taking time to prepare a well thought-out agreement when things are going well also helps solidify your relationship.
