Probate Related Question.

[notnutnut]

Good morning all, it's been a while since I was here last. I am the nominated executor of my mothers' will and the sole beneficiary. I haven't made the probate application as yet but will very shortly. I've lived here almost all my life since my parents bought to property. Am I legally entitled to prevent entry of my siblings onto the premises from now until probate is granted and title is transfered to myself please.
