This is all obviously worst case scenario thinking and have no current reason to believe OH would be unfair but you never know what the future holds.
Buying a property
Joint tenants in common with unequal shares
70% to me - paid in all cash
30% to my OH- all mortgage
But what would happen if a year in we spilt , would he get 30% of my cash when he had only paid a year of the mortgage ?
Also could he change his will at any time to leave for example his mother 20% of our property and I'm forced to sell it if he dies - is there a document we can get to insure on death our percentages will go to our partner.
Thanks for any advice !
