(e) Any other distribution as may be just and proper in all the circumstances.

(4) The court may award attorney fees on any motion filed pursuant to this section. The court shall award attorney fees to the moving party if the court finds that assets were intentionally concealed and thereby not included in the distribution of the marital estate.

(5)(a) A motion alleging inadvertent omission of assets must be filed within two years after the date of discovery of the omission but no later than three years after the entry of the judgment.

(b) A motion alleging intentional concealment of assets must be filed within two years after the date of discovery of the omission but no later than 10 years after the entry of the judgment.
