Thank you for the question. We unfortunately do not provide representation, however as the deceased resided in Scotland it will require to be a Confirmation. The Confirmation form is Form C1, the application for executorship would be made to the Sheriff Court. Being next of kid (while relevant in your case) does not actually have any legal weight. However I would advise having a solicitor do the applicant for the executorship on your behalf, they will need to assess the merits of your claim (but this should not be an issue) and the correct process and legal reasons for application must be applied. The fee for this confirmation will be £266.
I shall provide you with a helpful link that will assist you in finding a solicitor/representative near your local area. This will provide you with someone nearby your area who can assist you if required.
I hope this information proved helpful. You will find a local solicitor who deals with these matters on the law society webpage which is as follows;
