Sims 4 Married Sims Reverting to Partners is addressed in Patch 1.128, with EA fixing the relationship change triggered by entering Create a Sim through Plan Outfits or Custom Tattoo planning.
Sims 4 Married Sims Reverting to Partners should no longer happen through those affected CAS routes after the September 22 update. If a couple was already altered before patching, check the relationship state in a backup copy before making further changes.

Sims 4 Married Sims Reverting to Partners is not being described as a broad relationship rebalance. It is a specific bug where married couples could lose the displayed Married status and appear as Partners after using certain CAS entry points.
Which CAS actions were linked to the bug?
EA specifically identifies Custom Tattoo planning and Plan Outfits. Sims 4 Married Sims Reverting to Partners therefore has a much narrower confirmed trigger than simply opening Create a Sim in any possible way.
The September 22 patch is intended to stop those two routes from changing the couple’s relationship status.
Does the fix restore already affected couples?
The Laundry List says married couples will no longer revert to Partners, but it does not explicitly explain whether Sims 4 Married Sims Reverting to Partners will automatically repair couples whose status was already changed in an older save.
Until the live patch notes or testing confirms restoration behaviour, back up the save before manually changing relationship data or using cheats to repair an affected household.
How this differs from the wider relationship changes
Sims 4 Married Sims Reverting to Partners is separate from Lovestruck Relationship Satisfaction and Growing Together Family Dynamics. Those systems are also being tuned on September 22, but they deal with satisfaction decay, inactive households, dynamics and autonomous behaviour rather than marital status being overwritten.
What to check after installing the update
After patching, test Plan Outfits or Custom Tattoo planning with a backed-up married household and confirm the relationship panel still shows the correct status. If Sims 4 Married Sims Reverting to Partners continues in a modded game, repeat the test without relationship and CAS mods before reporting the base game as still affected.
How to verify the change after the update
Once the patch is installed, test Sims 4 Married Sims Reverting to Partners in a backed-up or disposable save before changing several settings at once. Start without mods where possible, reproduce the exact behaviour the guide describes, and then restore compatible files gradually. This gives you a clean comparison between the official September 22 patch and anything being added by custom content or script mods.
If the result differs from the live Patch 1.128 behaviour, record the platform, game version and exact steps that reproduce it. Then repeat the test with mods removed so an outdated script or UI mod is not mistaken for a remaining base-game bug.
What to check in the live game
After the September 22 patch is installed, compare the behaviour in a backed-up save with a completely clean test save. Use the exact interaction, object or relationship state described above, then repeat the same steps with mods removed if the result is inconsistent. This makes it much easier to tell the difference between a base-game regression, an old save state and custom tuning that has not yet been updated.
Keep notes on the platform, game version and steps that reproduce the problem. Use the live Patch 1.128 behaviour as the new baseline. If an affected household still behaves differently, compare it with a clean test save and keep the exact reproduction steps ready for an EA Forums report.
The September 22 update is now live as Patch 1.128. EA previewed the changes in its official September 15 Laundry List, and the live patch confirms the fix is included. If the same symptom continues, test an unmodded save before treating it as a failed base-game fix.
Sims 4 Married Sims Reverting to Partners should now stop
Sims 4 Married Sims Reverting to Partners has a clear official fix scheduled for the September 22 update. The patch should stop Plan Outfits and Custom Tattoo planning from changing a married couple into Partners, while the live notes and post-patch testing will tell us whether previously affected households are repaired automatically.
