While my parents were alive my step-sister took 26,000.00 from their bank account and says she didn't keep any of it but 8,000 to pay for funeral and cremation and wont tell me where the rest of it is. Also, she locked me out of their home for a month and took everything. I have proof from her what she took and since they were MY bio parents and it was her mom and Step-dad I say when the house sells I get 3/4 and she says I am only going to get 1/2 less everything she took from the house. Plus the harassment from her while my mom was living with me (she called the cops on me every day). What can I do???
Is mom and dad's estate settled yet? Did it get split 50/50 or other?
In my best guess, you can't do anything without an attorney. The police aren't going to touch this, since it is your word against hers and may be difficult to prove (other than hearsay) that mom didn't gift her the money -- which sis may claim.
Wishing you luck in getting a settlement on this one. Shame on parents for not preparing a Will. Shame on parents for not fighting or placing a claim for that money when they learned it was taken from their accounts -- especially since you say this occurred while they were both still alive.
As for what you respectively get from the estate: that's not up to either of you, it should be in whichever will remains to be settled. If there's no will, whoever's appointed executor will decide; and if you each of you have the sense you were born with you'll accept what you're given and go your separate ways.
Seriously, drop it. These fights are NEVER worth it.
