Are you responsible for your estranged brothers funeral costs who you have not spoken to for ten years?

Generally, you are not legally responsible for a sibling's funeral costs if you haven't had a relationship or if there is no legal obligation, such as being named in a will or estate planning documents. However, laws can vary by jurisdiction, and if the deceased leaves behind no assets or designated beneficiaries, the responsibility may fall to the next of kin. It's best to consult with a legal expert to understand your specific obligations in this situation.
