When probating a Will in Solemn form, you must provide notice of such to any heirs or beneficiaries of the decedent. This allows them an opportunity to contest the Will should they chose to do so (assuming they have standing), and provides them with notice of any proceedings with regards to the Will. The term "person" likely refers to the heirs or beneficiaries of the decedent. As for whether or not the probate court will modify the notice requirements, this is dependent on any motions that are filed and the specific circumstances surrounding such. You should consult with an attorney who practices probate law to get more specific answers to your question(s).
