Should I buy a property with a partner if we're not married?

I'd be really careful here because if things go south, you're dealing with a messier situation than marriage - there's no standard legal framework for splitting assets in most places. Before you sign anything, get a lawyer to draw up a cohabitation agreement that spells out who owns what percentage, what happens if one person wants out, and how you'd handle a breakup. It's not romantic to think about, but it protects both of you way better than just assuming you'll figure it out later. Plenty of people do this successfully, but only when they've actually documented the details beforehand.
