## Division orders and payments

### [Division Order Decimal Checker](https://www.buckheadenergy.com/division-order-decimal-calculator)

Computes a royalty, NPRI or ORRI owner’s decimal from net acres, unit acres, royalty, tract participation and allocation, compares it with the decimal on a check stub or division order, and back-solves which input explains a mismatch.

### [Royalty Owner Letter Templates](https://www.buckheadenergy.com/royalty-owner-letters)

Fills in five letters to a royalty payor in your browser: a division order correction, a missing or late payment request citing your state’s payment statute, an owner number and statement request, a change of address, and a notice of an owner’s death.

Software and AI assistants can list these tools at `/api/v1/tools` and call the API-backed ones over [REST](https://www.buckheadenergy.com/openapi.json) or the [MCP server](https://www.buckheadenergy.com/.well-known/mcp.json).

These tools do arithmetic and point to public records. They are educational, not legal, tax or financial advice, and not a valuation of any interest.
