It is a stage of mitosis.
In telophase, the chromosomes separate into distinct new nuclei in the emerging daughter cells.

Telophase (sometimes spelled telephase) is a stage in either meiosis or mitosis in a eukaryotic cell reversing the effects of prophase and prometaphase events. During those events, the nucleus was dissolved and the chromatin in the cell was condensed into chromosomes. Telophase thus "cleans up" the secondary after effects of mitosis.
At this stage the non-kinetochore microtubules continue to lengthen, further elongating the cell. Corresponding sister chromosomes, which are the results of anaphase, attach at opposite ends of the cell. A new nuclear envelope, using fragments of the parent cell's nuclear membrane, forms around each set of separated sister chromosomes. Both sets of chromosomes, now surrounded by new nuclei, unfold back into chromatin.
Cytokinesis, if slated to occur, usually occurs at the same time the nuclear envelope is reforming, although they are distinct processes. In animal cells, a cleavage furrow develops where the metaphase plate used to be, pinching off the separated nuclei.
In plant cells, vesicles derived from the Golgi apparatus move to the middle of the cell along microtubules scaffold called the phragmoplast. This structure directs packets of cell wall materials which coalesce into a disk-shaped structure called a cell plate. The cell plate eventually develops into a proper cell wall, separating the two nuclei.
Each daughter cell has a complete copy of the genome of its parent cell, and mitosis is complete.

It is NOT when the membranes split- that is cytokinesis. Telophase is marked by the decondensing of chromatin and formation of nuclear membranes in the presumptive daughter cells. However, the formation of the cleavage furrow and split into daughter cells is not included in this stage.

In telophase, the chromosomes are cordoned off in distinct new nuclei in the emerging daughter cells.

Telophase: The daughter chromosomes arrive at the poles and the spindle fibers that have pulled them apart disappear.

it's when the 2 cell membranes completely separate, leaving you with 2 separate cells.
