When someone tries to trace an asbestos exposure back to the company that made or sold a product, the business name in old records may not match the company that exists today. The original manufacturer or supplier may have merged with another business, been acquired, changed its name or filed for bankruptcy. Those corporate changes can make it difficult to identify the companies connected to an exposure and determine where a claim may be directed.
Tracing that history often requires looking beyond the name on an old product, employment record or jobsite document. Corporate records can help connect a business to its successors, while information about acquisitions, asset sales and bankruptcy trusts can help clarify how asbestos-related liabilities were handled over time. An attorney experienced in asbestos litigation can help investigate those connections and determine which companies or trusts may be relevant to a claim.
The process isn’t always straightforward, particularly when a company’s history spans several mergers or changes in ownership. A company’s legal history may involve multiple corporate entities, making it important to examine how those changes affected its asbestos-related obligations.
Tracing Companies Through Corporate Changes
Companies that used asbestos throughout the 20th century had decades to reorganize. They changed names, merged with other businesses, sold assets or filed for bankruptcy. Those changes can make it difficult to identify the company connected to an old asbestos product or workplace exposure. Tracing that history can help identify who may be responsible for an old asbestos exposure.
Common Corporate Changes
- Asset sales
- Bankruptcies
- Mergers
- Name changes
Johns-Manville Corporation is one example. In 1981, the company shortened its name to Manville Corporation. A year later, it filed for bankruptcy because of overwhelming asbestos liability. The resulting Manville Trust later became a model for other asbestos bankruptcy trusts.
Honeywell’s history shows how mergers and acquisitions can add another layer. The company grew through decades of mergers, including one that created the Minneapolis-Honeywell Regulator Company. It later acquired Bendix, a brake manufacturer, and North American Refractories Company, a maker of industrial insulation materials. Both businesses had used asbestos in their products, and their asbestos liabilities followed Honeywell for decades after the acquisitions.
Successor Companies Can Inherit Claims
When one company buys or absorbs another, the acquiring company may inherit the seller’s legal responsibilities, including asbestos claims. Courts call this successor liability, and whether it applies depends on how the deal was structured and what the surviving company agreed to take on.
Honeywell’s relationship with Bendix is one example. Honeywell became Bendix’s successor-in-interest, taking on Bendix’s legal responsibilities for asbestos claims tied to Bendix brake products. In the early 2000s, Honeywell faced more than 40,000 asbestos lawsuits connected to a business it hadn’t originally built but had acquired.
That responsibility can shift again. In October 2025, Honeywell transferred its remaining Bendix and NARCO-related asbestos liabilities to Delticus, a newly formed company created to manage the legacy liability. Honeywell contributed about $1.68 billion in cash and insurance assets to fund the transfer, and Delticus took responsibility for handling current and future claims.
For someone tracing a decades-old asbestos exposure, the company responsible for a claim today may not be the company that made the product or employed the worker. The liability may have moved through several corporate owners before reaching the entity responsible for paying a claim.
A Different Route Through Bankruptcy
Bankruptcy doesn’t make asbestos claims disappear. Instead, companies that qualify under Section 524(g) of the Bankruptcy Code can reorganize their asbestos liabilities through a trust set up to pay current and future claimants. Congress added this section in 1994, largely in response to the Manville case, allowing asbestos liabilities to be transferred to a trust as part of a company’s bankruptcy reorganization while preserving a source of payment for asbestos claims.
Since 1994, more than 60 companies have used this process, and asbestos trust funds have paid out billions of dollars. The Manville Trust itself started with $2.5 billion when it became operational in 1988.
As attorney Daniel Wasserberg, co-founder of Meirowitz & Wasserberg, explains, “There are a whole bunch of companies that have filed for bankruptcy under a very special code. It allows for companies with asbestos liabilities to reorganize, set aside money, and go on with their corporate life, without having to be sued anymore. They set up their own trust. They have their own trust distribution procedures.”
Connecting Asbestos Exposure to a Company
Corporate history only becomes useful when it can be connected to an actual exposure. Identifying which company made, sold or used the asbestos product someone came into contact with can be one of the most difficult parts of building a claim.
Attorneys typically rely on employment records, product invoices, workplace safety documents and corporate histories to make that connection. A person’s job title, worksite and the years they worked there can help narrow down which companies, or their successors, may be responsible.
People diagnosed with an asbestos-related illness, including mesothelioma, often don’t know the full corporate history behind their exposure. An attorney experienced in asbestos litigation can trace a company’s name changes, mergers and bankruptcies to determine which entity may be responsible for a claim today, even when the original company no longer exists under its old name.
