I'm trying to split polygons with overlaping line features, using Split Polygons tool from Topology toolbar. The problem I encounter is that only one from new polygons have old attributes and others only null values. I'm using arcgis 10.1.

That can be managed with the split/merge policy.
I believe that domains would be required to enable this functionality.
take a look at the split policy in the domain section of help

Split policies

An attribute for any given table, feature class, or subtype can have one of three split policies that control the value of an attribute in the output object:

  • Default value—The attributes of the two resulting features take on the default value for the attribute of the given feature class or subtype.

  • Duplicate—The attribute of the two resulting features takes on a copy of the original object's attribute value.

  • Geometry ratio—The attributes of resulting features are a ratio of the original feature's value. The ratio is based on the ratio in which the original geometry is divided. If the geometry is divided equally, each new feature's attribute gets one-half of the value of the original object's attribute. Geometry ratio policies only apply to domains for numeric field types.

In the parcel example above, when a parcel is split, the Area attribute is automatically assigned as a property of the resulting geometry. The value for Owner is copied to the new objects (in this database, splitting a parcel does not affect its ownership). The PropertyTax is calculated based on the area, or size, of a parcel. To calculate the PropertyTax for each of the new objects, the split policy divides the PropertyTax of the original parcel proportionally among the new features according to their area.

If you do much topology you should already be aware of the topology rules.
