lMy ex partner and i split up 2 years ago. My partner wants 15000 to buy her out. I need to remortgage but my new partner is able to get a better % rate as has not got any arrears. This would be in her name. How do i protect my property in that all sh

Pre-nups are not always recognised in this country but if you broke up after a reasonably short period, that would be taken into account, otherwise its a matter of taking a chance with the knowledge that if things go wrong the new lady will be eligible to half of it, possibly.

you simply make an joint application for a re-mortgage if possible and therefore it will be like a purchase,

Your new partner cannot raise finance on your property because she is not the proprietor and cannot incumber the legal title.

At this stage there is nothing you need to do, because the joint property will automatically have one restriction on the declaration of trust and secondly one from your mortgagee.
