Separate Accounting for Trust-Owned Businesses
Trusts sometimes hold more than investment portfolios. A family trust might own a ranch, a small business, rental properties, or mineral rights. Managing these operations alongside traditional trust assets can get complicated. This statute gives the trustee a practical tool: the ability to maintain separate books for any business or activity within the trust.
If a trustee who conducts a business or other activity determines that it is in the best interest of all of the beneficiaries to account separately for the business or activity instead of accounting for it as part of the trust's general accounting records, the trustee may maintain separate accounting records for its transactions, whether or not its assets are segregated from other trust assets.
A.R.S. § 14-7412(A)This flexibility matters because business operations have their own cash flow rhythms. A farming operation might need to retain cash for equipment or seed. A rental property might need reserves for maintenance. Lumping everything together with the trust's investment income would make it difficult to manage either properly.
Deciding What Stays in the Business
The trustee decides how much of the business's net cash receipts should be kept for working capital, fixed asset replacement, and other foreseeable business needs. Whatever remains gets classified as either principal or income in the trust's general records. If the trustee sells business assets outside the ordinary course of operations, the net proceeds go to principal.
The statute specifically lists the types of activities eligible for separate accounting: retail, manufacturing, service businesses, farming, livestock, rental property management, mineral extraction, and timber operations. This broad coverage reflects the reality that Arizona trusts frequently hold diverse assets. Proper separate accounting protects both current income beneficiaries and future remainder beneficiaries by keeping business decisions transparent and well documented. Experienced estate planning counsel can help trustees set up these accounting structures correctly from the start.
