Sample "Owner Occupier Tenancy Agreement" wanted if possible

[jpkeates]

I thought the 'Owner Occupier Tenancy Agreement' covered the situation because I will continue to live in the property.

That's not what the one's I've ever seen (which is a limited number!) do.

I think you might helpfully describe the arrangement you have in mind, then I'm sure someone can point you at an appropriate example.

Things that matter (as well as you living in the property as well) are what parts will you keep separate for individual use and which will you share (if any)?
Will any of the separate area for the other person have cooking facilities?

To be honest, though, if you're sharing the property with someone and you own it, giving them a right to live there for 15 years is going to be tricky.
