The affidavit of foreign law (precedent in Tristram) is now called a statement. It should be signed by a solicitor in Scotland which can confirm that the will is valid and is prepared in accordance with the laws and constitution of Scotland.
The whole issue of the resolution of conflict of laws and procedures within the United Kingdom is ever-present as is the derivatives of the House of Lords decision in Udny v Udny.
Thank you Gina, we now have a Scottish solicitor on board to provide a statement. Were you able to apply for probate online or does this require a paper application?
