It is the sole responsibility of the person named as the executor to distribute the monies in a responsible manner when there is a situation where the deceased has had a will made. In cases where a solicitor or a bureau is handling the Will then they would have to talk to the beneficiaries in person. This will allow for proper and meticulous payment arrangement in a timely manner. In cases where the executor himself takes care of all the other paper work, then they would need to talk to communicate with the beneficiaries.
If there is any doubt regarding the allowance of the money due, you always have the right to be granted a probate issued by the probate registry. This would also include the Will. This process will brief you about the Will left behind by the deceased, its contents and also will tell you who the executor is.
In situations where a Will was not created, then the distribution of estate will be according to rules defined by default. If this is the case you might find out that inheritance that is due to you may not reach you. A copy of letter of administration can be obtained will is going to have all that information about the estate administrator.
Now if the estate is rather small and the probate grants do not need letters of administration, you may not get to know the name of the executor and so you may have to research and investigate further to understand and confirm that you will in fact be provided with the inheritance. Usually it turns out that the Will executor is the next of kin to the deceased and so you can start with that.
You can request for a proper clarification in situations where you feel that the Will executor is holding back information or not providing you the entire picture. If the executor fails to respond to you letter requesting clarification, you can go onto the procedure where a caveat is placed preventing them from representing so as to restrict the executor from getting hold of the document. This will take away their ability to release funds. When this is done the next of kin or executors will be warned and will then understand that they need to contact you for clarification. This caveat or warning can be withdrawn as soon as you have all your doubts cleared.
All these situations require proper guidance because it is not something you face on a daily basis. Only an experienced attorney will be able to provide proper guidance on the subject so that you understand all the technicalities perfectly.
