The Margolius Firm, LLC is a consulting firm consisting of the expertise of Philip N. Margolius and Alan M. Margolius. This family-oriented consulting team combines their skills and knowledge in business ventures, real estate, trust administration and management of private charitable foundations.

Trust Administration:
Acting as either Trustees or consultants to the Trustees, the Margolius Firm, LLC provides hands-on administration in the following areas:

  • Grantor Trusts – Grantor trusts are trusts where the grantor has a reversionary interest greater than five percent of the trust assets at the time of transfer of assets to the trust. If a trust is considered a grantor trust, the income from the trust will be taxed to the grantor, not to the trust itself. These trusts are very flexible and vary widely in asset amount, construction and management.
  • Investment Vehicle Trusts – these trusts are created so that a group of individuals (or parties) can invest together under one unified vehicle controlled by the trustee of the trust.
  • Testamentary Trusts – These trusts are created under an individual’s last will and testament. These trusts are very flexible and vary widely in asset amount, construction and management.
  • Life Insurance Trusts – these trusts are used in cases where an estate will be taxable or liquidity is paramount to ease of administration to an estate. A properly drafted and administered life insurance trust will not be includible in the estate of the trust’s creator.
  • Supplemental Needs Trusts – Supplemental needs trusts are compliant with provisions of US state and federal law and are designed to provide benefits to, and protect the assets of, individuals with physical, psychiatric, or intellectual disabilities, and still allow such persons to be qualified for and receive governmental benefit and health care benefits, especially long-term nursing care benefits, under the Medicaid welfare program. Supplemental or Special Needs Trusts are frequently used to receive an inheritance or personal injury litigation proceeds on behalf of an individual with a disability, in order to allow the person to continue qualify for Medicaid benefits and other governmental benefits and assistance.
