I'm sorry - this may be quite long but am looking for some advice please MN legal experts!!
My DF passed away 18 months ago. He was married to my stepmum who I feel hugely indebted to as she cared for him in his last years when he was unwell. We have always got along and I care for her very much. She and my dad owned a house which she continues to live in. I am an only child and my stepmum has two daughters; all of us adults and were adults when they married so were never brought up by our stepparents IYSWIM. I dont really have a relationship with either of my stepsisters and never have as we live in separate parts of the country.
My DF Will put his share of the house in trust, and as things stand when DSM passes away, 50% of the house proceeds will pass to me; 25% to each of my stepsisters. It has recently been brought up that prior to his death, DF and DSM agreed that this wasnt a fair split and that they had intended to change the will to reflect that each of us receive 33% of the proceeds. There wasnt enough time to action that before he died; and he and I never spoke about whether this was discussed. The house isnt worth very much - we are not talking about millions of pounds.
I am now being put under some pressure to agree to sign a declaration of trust to reflect a new 33% split of the proceeds of the house upon DSM passing away. I know that legally I can say no; but in my heart it feels that an equal share between all 3 of us is right and fair. I know my DSM is keen to ensure her children are treated equally to me when she passes and as I say, I feel hugely indebted to her so I dont want to cause undue stress over this.
The main complication for me in this, is that all of the above is being proposed via a solicitor who works at the firm as one of my stepsisters (SS1). My hunch is that there was never a conversation about this prior to my dad dying and that all of the above has stemmed from/is being pushed for by SS1 who (not wanting to do a massive drip feed!) does not have a great track record with money; was not a fan of my DF and has long manipulated and gaslighted my lovely DSM.
Whilst I feel that 33% each is a fairer split; I am nervous that this is all being handled by a colleague of someone who will directly financially benefit - it just feels off to me. I am reluctant to instruct my own solicitors and incur a load of fees to ensure it is all done above board when I am already standing to lose out financially. I am also not clear if there are any additional implications of breaking or changing the existing trust that has been set up - eg. if my DSM were to require proceeds from the house to pay for future care home fees; whether there are any tax implications for changing the trust etc etc. As I say the house is not worth that much and I worry about spending hundreds/thousands on the legal work needed to change the % split.
Any help or advice MN'ers can give for moving forward with this tricky situation would be great!
