Primary Beneficiaries, Eligibility
Any person or entity may be named as the primary beneficiary of your residuary estate or as the primary beneficiary of a specific gift.

You may name just one primary beneficiary to receive your entire residuary estate or you may also choose to name an unlimited number of primary beneficiaries to share your residuary estate.  However, if you are creating a will that gives your spouse less than one-third of your estate, your spouse may defeat your will's instructions by choosing to take the elective share provided by Pennsylvania law.
