Unjust enrichment can be applicable if you lent money to someone and he doesn’t want to return it. This is a very common case in Spain and we receive many queries regarding this:
“I assisted my father in the purchase of a Spanish Property. I initially loaned him the sum of 30,000 euros to assist him on the basis that if he sold the property, he would reimburse me. There was a falling out and it now transpires that he sold this property and purchased another apartment. Now, my father says that: “as soon as the market allows, no one will be more pleased than me, to sell the property and conclude this matter.” I want my loan back. I hold receipts from the Spanish bank amounting to 30,000 euros”.
The type of case we should deal with is a “claim for unjust enrichment” (in Spain it is called enriquecimiento sin causa o injusto). We have had many cases like this; it is very common between families. Someone makes a loan with good will and then he/she never receives the money back.
For claiming the loan back, we will only have to prove that the money reached your father’s bank account. In Spain, a loan can be never considered a donation, if someone receives a donation, it has to be declared as such.
So normally, if someone receives money from another one, it is considered a loan and it has to be returned.
If you lent money to someone without a signed loan agreement, you will be able to claim the loan back if you have evidence of the funds transferred to the borrower’s bank account.
