Difficulty with early notice of bond cancellation

On 7 May, my partner and I informed Standard Bank that she was giving early notice of bond cancellation, as the property associated with the bond account had been sold. A response was received and we were advised that the early notice letter needed to be signed by both parties on the bond account (as the letter had only been signed by her). We informed Standard Bank that the other party on the bond account was deceased.<br> <br> We were then advised to contact Deceased Recoveries. We did so, enquiring whether they would need the letter signed by the executor of the deceased parties' estate. No one has been able to advise and we have only received a standard autoresponse email - we have heard nothing since the beginning of June.<br> <br> We want to provide early notice that the bond will be cancelled as part of the sale of the property. We were advised that Standard Bank would penalise bond account holders if such notice was not given at least 90 days prior to the request from the transferring attorneys to cancel the bond. Who signs the letter if one of the parties on the account is deceased? Can anyone assist please?
