That\u2019s why it\u2019s important to understand exactly what is meant by a \u201cFormula AB Trust.\u201d A Formula AB Trust is a particular type of trust designated by California law and is often used to reduce estate taxes for individuals with considerable assets.<\/p>\n<h2>What Is a Formula AB Trust?<\/h2>\n<p>Broadly speaking, a trust is a financial arrangement in which one person, known as the \u201ctrustor,\u201d entrusts assets to another person, known as the \u201ctrustee,\u201d to be held and managed in trust for the beneficiaries. A Formula AB Trust arises as a result of California\u2019s <a href=\"https:\/\/legalpedia.ai\/articles\/understanding-community-property-in-the-modern-age\/\">community property<\/a> laws. Generally, California law provides that assets acquired during marriage are owned jointly by both spouses and, upon death, the <a href=\"https:\/\/legalpedia.ai\/articles\/understanding-what-a-surviving-spouse-means\/\">surviving spouse<\/a> is able to pass the assets directly to their heirs. This is because, under the <a href=\"https:\/\/legalpedia.ai\/articles\/understanding-community-property-in-the-modern-age\/\">community property<\/a> laws, the deceased spouse\u2019s share of the assets automatically transfers to the <a href=\"https:\/\/legalpedia.ai\/articles\/understanding-what-a-surviving-spouse-means\/\">surviving spouse<\/a>. To avoid this automatic transfer, some couples separate their assets into a Formula AB Trust. This trust splits the trustor\u2019s estate into two trusts \u2013 the A trust and the B trust.<\/p>\n<h2>How Does a Formula AB Trust Benefit Your <a href=\"https:\/\/legalpedia.ai\/articles\/what-is-estate-planning-and-how-can-it-help-you\/\">Estate Planning<\/a>?<\/h2>\n<p>A Formula AB Trust allows individuals to transfer assets to the two trusts and, upon the death of the first spouse, both the A trust and the B trust are identified by the individual\u2019s will. The A trust is for assets that would otherwise go to the surviving spouse, while the B trust is for assets that are intended to be passed to other beneficiaries (i.e., children, grandchildren, etc.). In this way, a Formula AB Trust can reduce estate taxes for individuals with considerable assets, as the B trust is generally subject to lower tax rates than the A trust.<\/p>\n<p class=\"legalpedia-cta-inline\"><em>Want to explore this concept further? <a href=\"https:\/\/legalpedia.ai\" target=\"_blank\">Ask Legalpedia AI<\/a> \u2014 get a plain-English explanation instantly, free.<\/em><\/p>\n<h2>Related Legal Concepts<\/h2>\n<p>Understanding Formula AB trusts often goes hand in hand with other sophisticated <a href=\"https:\/\/legalpedia.ai\/articles\/what-is-estate-planning-and-how-can-it-help-you\/\">estate planning<\/a> tools like QTIP trusts and qualified personal residence trusts (QPRT), which similarly help minimize estate tax exposure.
