Herencia cuenta bancaria

I'm sorry to hear about the loss of your grandfather. In terms of the situation you described, I am not a legal expert, but I can provide some general information. In many jurisdictions, the rules regarding inheritance and distribution of assets(https://captemp.pro/ ) can vary. It's essential to consult with a qualified attorney or seek legal advice specific to your region's laws. They will be able to provide accurate information and guidance on how the assets should be distributed according to the applicable legal framework. They can consider factors such as any will or testamentary documents, local inheritance laws, and the specific details of the savings account. It's important to ensure that everyone's rights and entitlements are respected during this difficult time.

Se debería repartir el dinero entre todos los herederos, aunque se presume que si es cotitular, la tercera parte es de ella.
Con lo cual si tienes medios de prueba para acreditar que la totalidad del dinero es del fallecido, que los otros cotitulares ni ingresaban dinero ni nada, aunque ficticiamente figuraran otras personas, puedes iniciar la vía judicial.
De todas formas intenta un arreglo con tu tía e intentad por todos los medios que no sea el Juez quien decida.

¿Cuántos “titulares” tiene esta cuenta? ¿Quiénes son?
