Mayla & Franco were legally married & had 4 siblings between them.
Franco passed away.
Mayla ended up having a relationship with Mon and were never legally married but had two siblings between them.
In May 1991 Mayla inherited a plot of land by means of Deed of Donation. It was stated on the deed that Mayla was widowed at the time of the donation and had used her maiden name on the documentation. The tax declaration of the said plot of land is also under Mayla's maiden name.
In April 1995 Mayla passed away.
Now, Mayla's siblings would like to have portions of the land as inheritance but confusion and disagreement has arose as to how the property should be divided amongst Mayla's 4 legitimate siblings and 2 siblings out of wed lock.
What is the legal and righteous way of dividing Mayla's plot of land amongs her siblings?
