No, if you volunteer to carry out someone's last wishes, you are NOT entitled to payment for it. Helping another person or doing a nice thing for them willingly--when there was no contractual or other obligation to do so--does not entitle one to compensation. d on what you write, they have no legal basis to seek money from you (assuming you did not enter into any contracts with them). That does not meant that one or another might not try to file a legal action--unfortunately, it's almost impossible to stop someone from filing a lawsuit--but based on what you write, you do not appear to be liable for any costs.
