If the deed that caused you to fall out isn’t that serious go make up and get your bits, but there are some things in life that you need to stand your ground on. So long as it’s something that you can put behind you all then do it.
I have a strained family on both sides hadn’t seen my father for 12 years then one my aunts turned up telling me he was dead, I was his next of kin being the eldest in a long line of kids he had and it was down to me to sort a funeral for a man I hadn’t seen in 12 years my 2 stepsisters who had seen him more than I had in that time was to young. I felt frustrated as I felt that I had lost any ability to ever find out why he was the way he was.
On the other side I have my mothers parents who I had seen and grew up my mothers father was like a father and not a grandparent to me, long story short on that one I will never speak to them again, I lost a child that they helped me with cost of funeral back when I wasn’t able to sort it for myself, when falling out started I went and asked them to for the deeds to my sons grave to be told get him dug up and moved, it never came to this and I managed to obtain the deeds with a little help from my brief. Needless to say I will never ever bother with them again and they live less time than it takes a kettle to boil from me.
So as others are saying if falling out was over something stupid then sort it out or you will regret it but if you have enough reason not to make it up then you need to say goodbye to the goods unless you can prove they are yours and you still want them back go see a solicitor if they wont let you have them.
Sorry for the long winded reply but I know that something’s you fall out with family for can never be fixed
