A will is not considered invalid just because the person who witnessed the signing of the will is incompetent to testify about it later.

If a witness to the will is given a gift in the will, they can still testify about the signing of the will, but the gift they receive is considered void.

If a creditor or their spouse witnesses a will that charges property with a debt, the charging provision is still valid, and they can still testify about the will.

Being an executor of a will does not make a person ineligible to testify about the will

Conveyance

If a testator (the person who makes the will) transfers or does something with the property after making the will, it does not affect the will's operation regarding any property that the testator had the power to dispose of by will at the time of their death.

Unless the will says otherwise, if the testator had a right or interest in property that was created by a contract, conveyance, or other act related to property that was included in the will, the recipient of that property under the will receives the testator's right or interest.

Sale of property in a will

Unless the will says otherwise, if the testator bequeaths the proceeds of the sale of property and receives those proceeds before their death, the bequest is not cancelled even if the proceeds are mixed with the testator's funds, as long as the proceeds can be traced

Unless the will says otherwise, any property that was included or intended to be included in a devise or bequest in the will but fails or becomes void (e.g., because the recipient died before the testator or the gift was illegal) is included in the residuary estate, if any, contained in the will.

• Unless the will says otherwise, a device of land also includes any leasehold interests the testator had in that land.
