According to the court decision...https://www.bailii.org/ew...ses/EWFC/HCJ/2018/77.html
She received a "nominal maintenance order" for 6 years...described by the judge as a safety net while she was getting herself better established. In most places you lose your right to maintenance if you remarry.
The 4K per child per year* (until they completely their respective school) won't be affected as that's for the kids not her...though Louis could take her to court for an adjustment depending on how their respective income changes (not that I'd recommend that he should begin as proceedings).
*In addition to the GDF paying for their schooling (boarding?) and medical expenses.
Their marital home is owned by ADB which offered Tessy the use of the home until Noah finishes his undergraduate education "irrespective of whether the wife remarries or cohabits in the interim." The judge altered this to include a provision that termination of this agreement is subject to 6 months notice. Whether she'll wish to remain in the house is another question (or even if she still lives there).
Spousal maintenance will end as is standard when someone remarries not that she was really getting anything anyway. Everything with the boys will stay the same unless either she or Louis petition the court for an adjustment order. And the house is technically fine but I wouldn't be surprised if she moves out (or even if she's already done so)...it's not like Frank isn't able to afford housing.
