In Pennsylvania, a person may die with or without having a will prepared. If a person has a will, it is important to make sure that the will was properly executed. If it is not, the courts may not honor the will if it is contested. To create a valid will in Pennsylvania, you must be at least 18 years old. The person making the will, commonly called the testator, must also be of sound mind at the time the will is created. Of course, the will must also be signed by the testator. In some situations where the testator is physically unable to sign, there may be an exception to this rule. Finally, the will must be witnessed, and this is usually done by two adults who are not named as beneficiaries under the will.
