Marital Waste in Wisconsin Divorce: Dissipation of Assets

When one spouse deliberately squanders marital assets — gambling away savings, spending lavishly on an affair partner, or destroying property out of spite — Wisconsin courts call it marital waste or dissipation of assets. The consequence: the court can credit the wasted amount back to the innocent spouse's share of the marital estate, effectively making the wasting spouse bear the full loss.

This matters because Wisconsin starts from a 50/50 presumption. Without a dissipation claim, both spouses absorb the loss equally. With a successful claim, the wasteful spouse absorbs it alone.

What Qualifies as Marital Waste

Not every expenditure you disagree with qualifies. Wisconsin courts look for intentional destruction or expenditure of marital funds for a non-marital purpose. Common examples:

• Affair spending: Hotels, gifts, travel, or financial support for a romantic partner using marital funds
• Gambling losses: Significant losses at casinos, sports betting, or stock speculation that resembles gambling
• Substance abuse spending: Large sums spent on drugs or alcohol to the detriment of the family
• Deliberate destruction: Damaging, hiding, or giving away marital property to reduce the estate
• Excessive gifts: Large transfers to family members or friends intended to move assets out of the marital estate
• Business sabotage: Deliberately running a marital business into the ground to reduce its division value

What Does NOT Qualify

• Reasonable spending on personal needs, even if expensive (clothing, hobbies)
• Bad investments made in good faith (a stock that tanked isn't waste)
• Expenditures both spouses previously agreed to
• Normal business losses from legitimate operations
• Legal fees incurred during the divorce process
• Living expenses during separation, even if they seem high

The key distinction: waste requires intentional or reckless spending that serves no marital purpose. Poor financial judgment alone isn't enough.

Proving Dissipation

The spouse alleging waste bears the initial burden of showing that marital funds were spent for a non-marital purpose. Once that threshold is met, the burden shifts to the spending spouse to prove the expenditure served a legitimate family purpose.

Evidence you'll need:

• Bank and credit card statements showing the suspicious transactions
• Timeline demonstrating the spending began around separation or the discovery of an affair
• Documentation that the spending spouse concealed the transactions
• Receipts, hotel records, or other proof of where the money went
• Comparison to historical spending patterns (a sudden spike is suspicious)

How Courts Handle Waste Claims

When the court finds dissipation occurred, it typically uses one of two remedies:

Add-back method: The court adds the wasted amount back to the marital estate as if it still existed, then divides the total (including the phantom amount) equally. The wasting spouse's share is reduced by the full amount of the waste.

Example: The marital estate is $400,000 after the waste. The court finds $50,000 was dissipated. It treats the estate as $450,000, divides equally ($225,000 each), but the wasting spouse only receives $175,000 from actual assets (their $225,000 minus the $50,000 they already squandered).

Unequal division: The court uses the dissipation as a factor justifying deviation from the 50/50 presumption under § 767.61(3), awarding a larger percentage to the innocent spouse.

Timing Matters

Courts scrutinize the timing of the alleged waste:

• During intact marriage: Harder to prove — both spouses had access to the funds and normal spending is expected
• After separation or affair discovery: Much stronger claim — spending marital funds for non-family purposes when the marriage is clearly ending
• After filing: Strongest case — both parties are on notice that assets must be preserved

Some Wisconsin courts use the "date of separation" as the starting point for waste analysis. Spending before that date faces a higher bar.

Preventing Waste During Divorce

If you suspect your spouse is dissipating assets:

1. Document everything — download bank statements, screenshot unusual transactions, photograph missing valuables
2. Request a temporary restraining order — Wisconsin courts can freeze accounts to prevent further dissipation
3. File for temporary orders immediately after filing the divorce petition
4. Notify financial institutions — some will flag unusual activity if you alert them to the pending divorce
