Hi Dani, I am new to this forum, too. But I have been researching this area for years. If you want to go into an investing partnership with your mum I believe the best way would be to form a company. That way the company purchases the property, not individuals and therefore you can be part of the investment (and property deed) through the company. It is also the best way to avoid disastrous personal litigation. Putting a discretionary trust with your company would also be a good idea, so find a good solicitor and get their advice on how to do this.
