Does an exector of a will have the right to restrict a guardian of a minor who is inheriting the property from going to the property Prior to full execution of the will.?

Yes, if it's too soon in the probate process to make distribution. An executor must collect and manage the assets of the estate during the probate process, which usually takes six months to a year. He/she must collect the assets and file an inventory with the court. During that process she/he must pay any debts or claims and file any state and federal estate tax returns if necessary. That must all be done BEFORE the executor can distribute any assets to the beneficiaries. The executor is in charge of the assets until they are free and clear of the probate process.
