Avantor Families: Why a Letter of Instruction Can Simplify Estate Planning

Healthcare Provider Update: Healthcare Provider for Avantor Avantor, Inc. is a leading global provider of mission-critical products and services primarily serving the biopharma and healthcare sectors, among others. While Avantor operates extensively within these fields, specific details regarding partnership with a healthcare provider are typically not publicly disclosed in standard documents. However, Avantor's contributions to healthcare are primarily through the supply of high-purity materials, advanced technologies, and crucial solutions for bioprocessing and scientific research, indicating that they do engage closely with healthcare providers as part of their operations. Expected Healthcare Cost Increases in 2026 As we look toward 2026, healthcare costs are anticipated to rise dramatically, with projections indicating an average increase of 75% in out-of-pocket premiums for Affordable Care Act (ACA) marketplace enrollees. This surge is due to a convergence of factors, including the expiration of enhanced federal premium subsidies and significant rate hikes from major insurers, with some states seeing requested increases over 60%. The Kaiser Family Foundation has warned that more than 22 million individuals could be affected, facing steep premiums amidst a backdrop of escalating medical costs, requiring consumers to prepare strategically now to mitigate the financial impact in the coming year.

Important Lessons

Estate planning documents like a will and a revocable trust are important, but they might not give your family all the information they need to handle your affairs when you pass away, especially for Avantor employees with complex benefits.

In addition to an estate plan, a letter of instruction can offer your loved ones more information about your assets and personal preferences.

A letter of instruction can contain additional details, such as burial plans and the placement of essential documents, but it should not conflict with your estate planning documents.

Your loved ones might not know who to call, where to find your assets, or how to recognize reputable creditors if something were to happen to you today. By providing clear, supplemental guidance, a letter of instruction can help reduce the stress and work involved in the estate administration process.

A Letter of Instruction: What Is It?

A letter of instruction is an informal document outlining your assets and last wishes, sent to an executor, personal representative, or family members. It adds helpful information not included in legally binding estate planning documents like a will or revocable trust. For Avantor employees managing multiple retirement and savings plans, a letter of instruction can help simplify administration for family members, even though it is not legally required.

Since this letter is informal, it can be updated without consulting an attorney as circumstances change over time. It can contain supplementary information that supports your estate plan, but it should not contradict anything in your legal estate planning documentation.

How to Compose an Instructional Letter

Funeral Plans

You might provide information about your preferred funeral or burial type, funeral home, clergy member, music, speakers, or tribute. You can also include details about pre-paid or pre-arranged funeral or burial plans and where related paperwork is located. Some people also provide biographical details—something Avantor retirees can include for clarity.

Crucial Records

You can note the location of your Social Security card, recent bank account statements, deeds, titles, mortgage documents, important records, and estate planning documents. Some individuals also indicate where to find recent tax returns, which may help identify assets or income sources. If these documents are stored in a lockbox or vault, providing access instructions may be helpful.

Contact Details for Financial Representatives

The names and contact information for bankers, tax preparers, lawyers, insurance agents, real estate agents, and financial advisors can be included in the letter. These professionals can assist with background information, asset identification, account transfers, and final tax filings.

Details of the Assets

You can list your assets’ locations, titling, identifying details, and current values. This may include real estate, stock certificates, savings bonds, annuities, time shares, bank accounts, brokerage accounts, retirement accounts, company interests, safe deposit boxes, life insurance, and personal belongings with monetary or sentimental value.

Computer Files and Online Accounts

You may wish to list your digital files and accounts and designate a successor in your estate planning documents to manage them, since state and federal laws may limit access without written approval. For Avantor retirees who store retirement and benefits information online, this documentation may help reduce challenges.

Details of Debt

You can include information regarding your debts, such as account numbers, balances, statements, and lender contact details.

Beneficiary Details

The beneficiaries listed in your estate plan, along with their contact details, may be included in the letter. This makes it easier for an executor to locate and communicate with those who will receive assets—an important step for families with Avantor retirement accounts.

Pets

You can specify who you want to care for your pets and any specific instructions if your estate documents do not mention them. You may also include your veterinarian’s contact information.

Distribution List for Personal Property

Some states allow individuals to draft a separate document listing specific items of tangible personal property and their intended recipients, as long as the will references the list. Even in states where this is not legally binding, a letter of instruction can still guide your executor and help minimize disagreements.

Private Notes and Clarification of Goals

Some people include private notes or explanations for their decisions regarding inheritance or financial principles. Although not legally binding, these notes can help prevent misunderstandings.

What Does a Letter of Instruction Not Need to Include?

A letter of instruction should not repeat information already found in your estate planning documents. It is intended to provide additional details only.

It also should not be used to make changes to legally enforceable estate documents. Informal updates are not binding and may create conflicts.

Where to Store Your Instruction Letter

You can keep a copy of the letter with your estate planning papers, provide one to your lawyer, or place it somewhere your family is likely to look first. You can also share a copy with your executor and discuss it with them if you feel comfortable. Updating the letter each year is useful as assets and personal information change—particularly for Avantor employees with evolving retirement benefits.
