Fulfilling or working as per a last will is a matter of law as it is duly executed before a notary and sometimes kept with a public trustee till the death of the person who executed such a last will. Those have to be done according to the law of that particular state and on the other hand death bed wishes are the last words that have been told by the deceased or a command made by him, if this was a written one major steps have to be taken but fulfilling a death bed wish has more to do with morals.
If it however is a good deed he/she asked from the person who was there it is better to fulfill those after their death as it was the last wish of the deceased. Therefore such have to be done in a more organized way, most of the times they are charitable things they ask them to do such as to give away his money to a children orphanage or to organize a lunch for a set of needy children, donate food, water and stationery for rural schools and so on.
There are instances where they ask a person to organize his funeral in a way they wish and to have quotes to be engraved on their tombstones and so on. These are end of the day wishes of the deceased and it is so promising if one can stick to his words. There are stonemasons who can take over a job as such and can come up with a nice output. Therefore that is the best way to get a work as such done. There are particular places that have gravestones for sale and therefore people can order or select whatever the style and size they want in order to engrave the deceased’s last quote of words or his/her wish. Therefore such moral activities can be done on behalf of them.
Moreover surprisingly there is a kind of human beings who go and design their tombstone just the way they want prior to their death and allow them to fix it on the cemetery garden. These are wishes of people and therefore such shall not be disrespected or taken for granted. If there is a legal background as mentioned above, his /her heirs have to involve or file an action in a particular court and take care of the estate and devolve it as per the last will and testament he/she has executed.
