Hoping someone can confirm for me the below. My partner and I have different perctanges on our mortgage as I put 95 percent of the deposit down. This was shown when we took on the mortgage and is clearly defined. We can over pay up to 10 percent each year with no costs doing so. I'm thinking to try over pay as much as possible, however I'm just wondering say something bad happened and we split in 2/3 years time. Would I be now owner of a higher percentage? Or at least would I be able to fight to show my input during the mortgage time has been higher than hers? Sounds like a terrible question but from parents experience, and my parents partners experiences with mortgages, I don't want to be another sicker that pays all this money in to lose it should something terrible happen.
