It is not as simple under Louisiana succession law as a majority rule in this instance. If the sucession is already open and there is an independent administrator or executor appointed, then they have the authority to make the sale unless another heir or legatee affirmatively pursues court action to stop and obtains an order to prevent the sale. If the succession is not being administered independently, but rather under the normal rules of administration, the administrator or executor would have to obtain court approval to sell real property. The niece could challenge the sale at that time. While the situation is not one of simple majority rule, a judge is very likely to take into account the majority agreement to sell, particularly if it is supported by testimony from a realtor or appraiser that the contemplated sale is reasonable under prevailing market conditions. The foregoing is intended as legal information concerning the question asked, but is not intended as legal advice upon which the requesting party may rely in guiding their actions. Rather, the requesting party should consult an attorney for a personal consultation and advice for a full consideration of their situation and rendition of legal advice. Additionally, by providing this general information I am not accepting any representation of the requesting party and I am specifically declining to form an attorney-client relationship with the requesting party unless agreed to later after further consultation and agreement.
