Whether the court ordered distribution concerning the assets of the deceased needs to be returned or not by the person who received such where a Will has been found depends upon how long ago was the distribution of the assets and how long was the given estate closed.If more than four (4) years, then the statute of limitations to contest the probate of the Will bars any claims of any beneficiary.From what you have written, if the probate has not been closed and a Will has been found, then those who are not named in the Will should be ordered to return the assets that they have received if the estate has not been closed for more than four (4) years.
