I track several assets where I have partial ownership, e.g. properties owned in a partnership. My Net Worth totals, for example, are never accurate as a result. Is there a clever way to adjust for this? Else I was planning on creating my own summary sheet based off the net worth or accounts tabs, and adjusting there. But was hoping to avoid that as I expect those to break and need to be updated whenever I add/remove/change accounts.
If the property account is linked, create a manual account called contra asset, a negative asset, representing what you do not own. If the property account is a manual account, then you can show only your piece or show at total value and use contra asset to subtract out what you do not own. I have used both methods depending on the situation. It all depends on how you want to see this on the balances sheet.
