If any interest in or claim to real estate or personal property is disposed of by deed or will for life, with a limitation in remainder over, and the same instrument confers expressly or by implication a power upon the life tenant in his lifetime or by will to dispose absolutely of such property, the limitation in remainder over shall not fail, or be defeated, except to the extent that the life tenant lawfully exercised such power of disposal. A deed of trust or mortgage executed by the life tenant shall not be construed to be an absolute disposition of the estate, unless such estate is sold under the deed of trust or mortgage. A power of disposal held by any person in a fiduciary capacity under an express trust in writing shall not be deemed to be held by such fiduciary in a beneficial capacity and shall not be construed in any manner to enlarge the beneficial interest otherwise given to him under such trust.
