Questão jurídica principal
Whether interim spousal maintenance should be lifted due to changed circumstances
Decisão extraída
The husband did not make it credible that the decisive circumstances had materially and durably changed, or that the earlier decision was based on erroneous facts.
Fundamentação extraída
The lawyer’s letter did not prove that no pension, disability, or insurance claims existed. The alleged grounds were either unresolved, foreseeable, or could have been raised in the earlier appeal against the August 2017 order; the modification procedure cannot replace an omitted remedy.
