Emily thought she had it all figured out. Twenty years with David, a comfortable life in Escondido, and a clear understanding – or so she believed – that they were building a shared future. No marriage certificate existed, but they’d pooled resources, bought a house together, and Emily even quit her job to manage their home and David’s burgeoning photography business. Then David died unexpectedly, leaving everything to his children from a prior relationship. Emily was devastated, not just by the loss of David, but by the fact that she was left with nothing. She’d sacrificed her career, poured her energy into his success, and now felt completely abandoned. The cost? Years of lost income, emotional distress, and a bruising legal battle to recover what she believed was rightfully hers.
As an estate planning attorney and CPA with over 35 years of experience, I’ve seen this scenario play out far too often. Couples who intentionally forgo marriage, believing a formal agreement isn’t necessary, are often left vulnerable when one partner passes away. This is where a “Marvin Claim” – formally known as a claim for implied contract – comes into play. It’s a complex area of law, and navigating it within the context of probate can be especially challenging.
What exactly is a Marvin Claim? California case law, established in the landmark Marvin v. Marvin case, allows unmarried couples to enforce agreements made regarding property rights, even in the absence of a written contract. The burden of proof rests on the claimant – Emily, in this case – to demonstrate that an agreement, either express or implied, existed. This means proving a mutual understanding of shared finances and intentions. “Express” agreements are simple: a clear, documented promise. More often, however, these claims rely on “implied” agreements, which require a significant amount of evidence to substantiate.
What Kind of Evidence is Needed to Prove a Marvin Claim?

This is the critical question, and where many claims fall apart. Simply being a long-term partner isn’t enough. The court will look for evidence demonstrating a meeting of the minds – a clear, mutual understanding about how assets would be divided in the event of a separation or death. This can include:
- Financial Records: Joint bank accounts, shared investments, and documentation of who contributed what to the purchase of assets like the house.
- Communications: Emails, texts, and even handwritten notes discussing financial arrangements or future plans. Statements about shared ownership or supporting each other’s careers are invaluable.
- Testimony: Statements from friends, family, or business associates who can corroborate the understanding between the couple.
- Transferred Assets: Evidence of assets intentionally transferred to each other with the understanding they were held jointly.
The more corroborating evidence Emily can gather, the stronger her case will be. However, simply showing that she contributed financially isn’t enough. She must prove David intended to share those assets with her.
Why a CPA’s Expertise is Crucial in Marvin Claims
This is where my dual background as an attorney and a CPA becomes invaluable. Marvin Claims often hinge on complex financial issues, and understanding the tax implications is critical. For example, if Emily is successful in recovering an interest in the house, what is the “cost basis” of that interest? Will she be subject to capital gains taxes when she eventually sells it? The “step-up in basis” rules, which apply to inherited assets, generally don’t apply to Marvin Claims. This can result in a significant tax liability, and a proper valuation of the assets is essential. A qualified CPA can help determine the true value of the assets, calculate potential tax consequences, and ensure Emily makes informed decisions.
How Does a Marvin Claim Proceed Within Probate?
Unlike a traditional breach of contract lawsuit, a Marvin Claim is typically brought as a petition within the probate proceeding itself. This means filing a Probate Code § 850 Petition seeking a determination of Emily’s rights to the estate’s assets. The court will then hold a trial, and Emily will need to present her evidence and convince the judge that an agreement existed. It’s a complex process, and the executor of the estate will likely vigorously defend against the claim. The executor has a fiduciary duty to the beneficiaries of the will, meaning they must protect the estate’s assets.
What Happens if the Executor Fights the Claim?
If the executor disputes the claim, things can get contentious. The discovery process – the exchange of information between parties – will become crucial. Emily will be able to use Probate Code § 1000 to issue Subpoenas for bank records, David’s business files, and any other relevant documentation. She may also be able to compel Depositions of the executor, David’s children, and other witnesses. It’s important to be prepared for a potentially lengthy and expensive legal battle.
What if David’s Children Are Accusing Emily of Undue Influence?
Unfortunately, it’s common for the beneficiaries of the estate to accuse the claimant of pressuring or manipulating the deceased. In California, gifts to caregivers of dependent adults are presumed invalid under Probate Code § 21380. While this section generally applies to professional caregivers, the principle can be extended to personal relationships, particularly if Emily was providing David with significant care. This shifts the burden of proof to Emily to demonstrate that any gifts or financial arrangements were not the result of coercion.
Who Pays for All of This?
Legal fees can quickly mount in a Marvin Claim. Generally, an executor is entitled to use estate funds to defend the estate against claims like Emily’s (Probate Code § 8250). However, if the executor is defending their own actions – for example, if they are accused of mismanagement – they may have to pay their own legal fees unless they prevail. It’s a complex issue, and it’s important to have a clear understanding of the costs involved before proceeding.
Emily’s case is a reminder that failing to formalize financial agreements can have devastating consequences. While a Marvin Claim offers a potential path to recovery, it’s a challenging legal battle that requires strong evidence, a thorough understanding of California law, and the expertise of both an experienced attorney and a CPA.
What causes California probate cases to spiral into delay, disputes, and extra cost?
Success in probate court depends less on the size of the estate and more on the accuracy of the petition and the behavior of the fiduciary. Whether the issue is a forgotten asset, a contested creditor claim, or a disagreement among siblings, understanding the procedural triggers for court intervention is the best defense against prolonged administration.
- Escalation: Prepare for probate litigation if agreement fails.
- Document Challenges: Understand the grounds for contesting a will.
- Cross-Over: Navigate complex trust litigation in probate.
California probate is most manageable when authority is documented early, assets are classified correctly, and procedure is followed consistently from petition through closing. When the process is approached with realistic expectations about notice, claims, accounting, and dispute risk, the estate is more likely to move toward closure without avoidable conflict or delay.
Verified Authority on California Probate Litigation
-
Double Damages (Bad Faith Taking): California Probate Code § 859
The “nuclear option” of probate litigation. If the court finds that a person has in bad faith wrongfully taken, concealed, or disposed of property belonging to the estate, the judge may assess liability for twice the value of the property, in addition to recovering the asset itself. -
Grounds for Removal of Executor: California Probate Code § 8502
This statute lists the specific legal reasons a judge can fire a Personal Representative. Common grounds include wasting or mismanaging assets, neglecting the estate (moving too slow), or having an incurable conflict of interest with the beneficiaries. -
The “850 Petition” (Title Disputes): California Probate Code § 850
Probate litigation often revolves around ownership. This powerful petition allows the probate court to solve title disputes without filing a separate civil lawsuit. It is used when an asset is titled to a third party but belongs to the estate (or vice versa). -
Presumption of Undue Influence (Caregivers): California Probate Code § 21380
To prevent elder abuse, California law makes it incredibly difficult for paid caregivers to inherit from their patients. The law presumes the gift was the result of undue influence, forcing the caregiver to prove their innocence in court, often requiring a “Certificate of Independent Review.” -
Civil Discovery Rules Apply: California Probate Code § 1000
Probate is not just administrative; it is a court of law. This code section confirms that the standard rules of civil practice apply. This means litigators can use interrogatories, depositions, and demands for production of documents to build their case against a rogue executor. -
Extraordinary Fees (Litigation Costs): California Probate Code § 10811
Litigation is not covered by the standard statutory fee. Attorneys can petition the court for “extraordinary fees” for litigation services (e.g., defending a will contest or recovering stolen property). These fees are billed hourly and must be approved by the judge.
