Hi Emily, Assuming that you and your partner are in a long term relationship I would think joint tenants would be a better option. You could have your solicitor draw up a declaration of trust stating what amount you put in to the deposit etc and keep individual bank accounts so there is a easy paper trail of who paid what towards the mortgage in the event of a split. Going down the tenants in common route you are going to have to be specific with the land registry of each of your percentage of ownership. Looks like that will vary over time as you would have the larger holding at the start but then in future your partner would be gaining equity by paying the mortgage. https://www.which.co.uk/money/mortgages-and-property/first-time-buyers/buying-a-home/tenants-in-common-vs-joint-tenancy-amlkh0x4ct97
