Fake Partnership Stakes Sold to Churchgoing Retirees: SEC Sues Former LeFever Mattson CEO Kenneth Mattson

Published Oct. 12, 2026. Case statuses are current as of that date, based on SEC records.

The real estate partnerships were real. According to the Securities and Exchange Commission, the stakes many investors bought in them were not.

On May 22, 2025, the SEC charged San Francisco Bay Area resident Kenneth Mattson, former CEO of real estate investment business LeFever Mattson, with defrauding about 200 investors of at least $46 million by selling them fake interests in real estate limited partnerships. Many of the investors, the SEC says, were retired senior citizens Mattson met through his church community [1].

What the SEC alleges

According to the complaint, filed in the U.S. District Court for the Northern District of California [1][2]:

• Real partnerships, fake stakes. LeFever Mattson managed legitimate limited partnerships that owned residential and commercial real estate and had real investors. From about 2007 to April 2024, Mattson allegedly sold fake ownership interests in them.
• No ownership. The fake sales weren't recorded in the partnerships' legitimate ownership records, and buyers never became limited partners or received ownership rights.
• Ponzi-like payments. Mattson allegedly commingled new investor money with personal and business funds, used it to pay earlier investors, gave investors false tax records, and spent investor funds on personal expenses and on deals for his own partnership, KS Mattson Partners LP, which is named as a relief defendant (not accused of wrongdoing).
• Retirement savings. The SEC says Mattson persuaded investors to move money from their IRAs into so-called self-directed IRAs so they could buy the purported interests.

"As our complaint alleges, Mattson lied to hundreds of individual investors, many of whom were retirees investing their hard-earned savings, and did not actually sell them the ownership interests that he promised," said Sam Waldon, then acting director of the SEC's Division of Enforcement [1].

Charges and status

The SEC charges Mattson with violating the antifraud and registration provisions of the federal securities laws, and seeks permanent injunctions including a conduct-based injunction, disgorgement with interest, civil penalties and an officer-and-director bar [1][3]. The U.S. Attorney's Office for the Northern District of California announced criminal charges against Mattson the same day [1]; he is presumed innocent of those charges unless proven guilty. As of Oct. 12, 2026, we found no later SEC judgment on sec.gov.

Self-directed IRAs

A self-directed IRA can legally hold private investments, but custodians generally don't check whether the investment is real. The SEC has issued an investor alert on self-directed IRA fraud [1].

What an SEC civil case is (and isn't)

The SEC is a civil regulator. When it "charges" someone, it files a lawsuit in federal court or brings an administrative proceeding asking for remedies such as injunctions, repayment of allegedly ill-gotten gains (disgorgement), civil money penalties and industry bars. It cannot send anyone to prison. Criminal charges, when there are any, are brought separately by federal prosecutors, and a defendant in a criminal case is presumed innocent unless and until proven guilty.

Allegations in an SEC complaint are claims the agency must prove in court unless a defendant settles. When a defendant settles "without admitting or denying" the allegations, the court or the Commission enters an order, but the defendant has not conceded that the allegations are true. Throughout this article, statements about what happened are allegations or findings as described by the SEC, not established facts, unless we say a court entered a judgment or a defendant pleaded guilty.

Red flags in this case

• Being asked to move retirement money into a self-directed IRA to buy a private deal.
• Ownership you can't confirm with the partnership or a county record.
• A pitch that comes through church or community relationships.

How to check an investment before you hand over money

• Look up the person and the firm on Investor.gov and FINRA BrokerCheck. A clean search is not proof of legitimacy, but a missing or mismatched record is a reason to stop.
• Read the offering documents yourself, and ask a fee-only professional you found independently to read them too.
• Be skeptical of "guaranteed" or fixed high returns. Real investments carry risk, and promises of safety plus high yield are a classic warning sign.
• Be wary of pressure. Deadlines, "limited allocations" and repeated calls are sales tactics, not investment analysis.
• Don't let trust in a group replace due diligence. Fraud often spreads through churches, ethnic and professional communities, online chat groups and friends-of-friends referrals.

If you think you were affected

1. Keep everything: account statements, emails, texts, wire and payment records, and any marketing material.
2. Report it to the SEC at sec.gov/tcr. If a criminal case is involved, you can also contact the FBI at ic3.gov or the prosecutors' victim-witness office.
3. Watch for a receiver or fair fund. In some SEC cases, money is later returned to harmed investors through a court-appointed receiver or a distribution fund. Notices are posted on sec.gov.
4. Beware of "recovery" offers. People who lost money are often targeted again by scammers promising to recover it for an upfront fee. Legitimate receivers and the SEC do not charge you to file a claim.
